Could anyone please tell me where I can get wiring diagrams for an early 90s TRX 300 2x4 and a mid 80s TRX 250? I am trying to fix an ATV for a freind, he has put a 90s TRX 300 engine in an 80s TRX 250 frame and can't get a spark using the TRX 250 wiring loom. I think these two bikes have different types of ignition systems, one stator and the other electronic and I will need a TRX 300 wiring loom, HT coil and CDI?

Thanks!
